APPARATUS FOR COLLECTING AND DIFFUSING HEAT.

SPECIFICATION forming part of Letters Patent No. 385,571, dated July 3,1888.

Application filed November 2, 1887. Serial No. 254.103. (No model.)Patented in England January 1-1. 1885, No. 518.

To all whom, it may concern:

Be it known that I, THOMAS PIcKUP, asubject of the Queen of GreatBritain, residing at 43 Springfield Road, Burnley, in'the county ofLancaster, England, grocer, have invented certain new and usefulImprovements in Apparatus for Collecting and Diffusing Heat, (for whichI have obtained a patent in Great Britain, No. 518, bearing date January14:, 1885,) of which the following is a specification.

This invention has for its object to provide novel means for heatingrooms or apartments by the gases generated in a fire-place, stove, orrange in a room below.

To such end my invention consists in the features of construction andcombination of devices hereinafter described and claimed, referencebeing made to the accompanying drawings, in which Figure 1 is a frontelevation of the heatingdrum or heat receiver and diffuser; Fig. 2, avertical central sectional view of the same; Fig. 3, a front elevationof a fireplace provided with the gas collector 'and conductor, and Fig.4 a vertical central sectional view of the same.

In the accompanying drawings, a is a chamber situated at the back of thefire-place b, and provided with openings or vertical spaces 12, as shownin Fig. 2. These openings or spaces are presented to the back portion ofthe fire, but sufficiently below the surface of such fire that theheated gases evolved by distillation will flow through the openings orslits into the chamber a comparatively free from smoke. I am perfectlyaware that for this purpose a perforated diaphragm has been employed todivide the lower part of the chimney-flue into two portions, consistingof a front fire-space and a back circulating-space, in which the heatedgases from the firespace divide themselves on each side of the diaphragmand immediately mingle with each other above the throat of the chimneywithout any further utilization.

Now, the primary object of this invention is to utilize the waste heatby conveying the gases collecting or circulating in the chamber athrough a pipe, channel, or flue, c, to a heating-drum or heat receiverand diffuser, as

shown in Figs. land 2. The drum comprises a casing divided into threecompartments,f, g, and h, by surface-plates cl and e. The number ofcompartments may, however, if desired, be augmented or diminished by theapplication of more or less surface-plates. The heated gases are led orconducted by pipe 0 into the receiver, where, after traversing the lowercompartment, f, they pass upward through the opening (2' and along thecompartment g to the opening e, from whence they are conveyed along thechamber h to the exit-pipe f and chimney m.

The heated gases traversi ng through the compartments alternately, asabove described,will

impart heat to the surface-plates and side walls of the apparatus, andinsure a regular trans mission and conduction of heat into the room.

The grate or fire-space n is provided in which fuel may be deposited andburned when the kitchen-range or fireplace is not in use. When such isthe case, the damper o (previously closed) is opened to allow the heatedgases from the grate n to circulate in the chambers f, g, and h and heatthe surface-plates and side walls of the receiver or stove insubstitution of or in addition to the heated gases from thekitchen-range or fire-place.

The gases passing through the receiver, al though collected as free aspossible from smoke, will carry into the receiver and deposit upon thesurface-plate soot, which, accumulating and being a non-conduotingsubstance, would, if not removed, seriously obstruct the heating effectof the gases upon the surface-plates and side walls of the apparatus.

To clean the interior thoroughly of soot which may from time to timeaccumulate, I provide the doors as shown in Figs. 1 and 3, through whicha brush, rake, or other suitable instrument may be inserted.

A. damper or valve, k, (shown in Fig. 4,) may be used to regulate andcontrol the flow of heated gases into the receiver.

Having thus described my invention,what I claim is- 1. The combination,with the drum-casing, of the alternating surfaceplates m, d, and c, thebottom plate, at, having the draft-orifice n, the damper 0, for openingand closing the said orifice, and the fire-grate a, located in thedrum-easing beneath said bottom plate, sub stantially as described.

2. The combination, with the drum casing, the alternating surface-platesm, d, and e, the bottom plate, via-having the draft-orifice n, thedamper 0, for opening and closing said orifice, the fire-grate 10,located in the drumcasing below said bottom plate, the fireplace b, thegas-collecting chamber a, the passages 1/, receiving the gases from thefire-place and leading such gases into the chamber and thegas-conducting flue 0, leading from the chamber into the drum directlyabove the bottom plate therein, substantially as described.

3. The combination of aiire-place, b, a chamber, a, arranged adjacentthereto and receiving therefrom the gases arising from combustion, and agas-conducting flue, 0, leading from the gas collecting chamber to anapartment to be heated, with a heat receiver and diffuser located insaid apartment and connected with the gasconducting flue, substantiallyas described.

4. The combination of a fireplace, 6, a gascolleeting chamber having itsforward portion provided with vertical passages b, for receiving thegases from the rear of the-fireplace and leading them into the chamber,and a gaseondueting fine, 0, leading from the chamber to an apartment tobe heated with a heat receiver and diffuser located in said apartmentand connected with the flue, substantially as described.
